[Bug 1879080] [NEW] error message when installing pyodbc in a venv

[Jeff]

Public bug reported:

I have a fresh install of Ubuntu 20.04. I have the following packages
installed:

python3-venv
python3-pip
python3-wheel
unixodbc-dev

If I run these commands:

python3 -m venv ./test_env
. ./test_env/bin/activate
pip3 install pyodbc

This is the output I get. The package does seem to install successfully,
in spite of the fact that this is an error, not a warning.

Note that I do not get this error if I install pyodbc outside the venv.
Also, if I install it outside the venv FIRST, then pip will cache the
wheel package and use it when installing in the venv, and I don't get
the above error in that case.
